What we printed today! This was a monster print. PBT is used extensively in the electrical industry and remains largely undiscovered in the 3d printer world. The PC-PBT (https://www.sabic-ip.com/gep/Plastics/en/ProductsAndServices/ProductLine/xenoy.html) has amazing strength and stiffness, but for a print this large it requires a HOT chamber. We ran at 100C for the duration of the print.
